To which in upper mold (5) and lower die (12) clamping process, mode (8) can be nested in coined groove (13) to complete casting
Die casting production, while the positioning column (10) of insert (9) interior fixing assembling is plugged on lower die (12) with the movement of upper mold (5)
On location hole (15), guarantee the goodness of fit of upper mold (5) and lower die (12), reduce the parting line dislocation of upper mold (5) and lower die (12),
Ball bearing guide bushing (6) slides on ball guide post (7) simultaneously, can play the role of precise positioning when workpiece is punched, can make
The die casting precision of workpiece is higher, improves the precision of product, reduces product rejection rate, improves productivity effect；
S2: while, for water supply pump (18) and reflux water pump (19), can promote to supply in this way by singlechip controller (24) starting
Water in water tank (17) is imported into water-cooling ring (16) by water supply pump (18) by water inlet pipe (20), to realize to lower die (12)
It is cooling, so that casting heat quickly transmits, have the function that quick casting, while the water that the water pump that flows back (19) completes heat exchange
It is flowed into water tank (17) by return pipe (21), is recycled with realizing, increase the cooling way to lower die (12), improved
The die casting efficiency of casting；
S3: it is inside contracted after the completion of Die-Casting by singlechip controller (24) control lifting electric telescopic rod (4), to drive
Upper mold (5) resets, and then controls discharging electric telescopic rod group (22) overhanging drive gripper equipment (23) and is moved on lower die (12)
Side is inserted in the discharging for realizing casting in craft step (14) by two groups of gripper equipments (23), set on the die joint of lower die (12)
Craft step (14) are set, the part that casting is located at lower die (12) die joint can be completely encapsulated in inside die joint, avoid casting
Part slips, and plays the role of preventing mold from weighing wounded, in the case where identical operation guidance, reduces the frequency that mold weighs wounded, improves
The stability of product quality, reduces manufacturing cost, and advantage is that effectively reducing mold weighs the maintenance frequency wounded, improves formed product
Quality reduces production cost；
S4: after the completion of gripper equipment (23) discharging, singlechip controller (24) can promote discharging electric telescopic rod group (22)
It resets, while controlling and stopping working for water supply pump (18) and reflux water pump (19), to wait next work order.
